PUMP-ROD ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 766,751, dated August 2, 1904.

Application filed December 8, 1903. Serial No. 184,286. (No model.)

To all whom it may concern.-

7 Be it known that I, ALFRED ANDERSON, a citizen of the United States,residing at Detroit City, in the county of Becker and State of Minnesota, have invented certain new and useful Improvements in Pump-Rod Attachments, of which the following is a specification.

This invention relates to an attachment to be applied to coupling devices connecting pump-rods operatively with windmills or analogous actuators.

The attachment consists, essentially, of a holder which carries a loclepin adapted to engage the pump-rod and to be thrown out of engagement with the said rods, the latter operation being adapted to permit connection of the pump-rod with manual-operated means actuating same or discontinuing the movement of the said rod entirely.

For a full description of the inventionand the merits thereof and also to acquire a knowledge of the details of construction of the means for effecting the result reference is to be had to the following description and drawings hereto attached.

\Vhile the essential and characteristic features of the invention are susceptible of modification, still the preferred embodiment of the invention is illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the attachment applied. Fig. 2 is a vertical sectional view through the coupling attachment and adjacent parts. Fig. 3 is a side elevation showing the pump-handle operatively connected with the piimpa'ocl. Fig. 4: is an enlarged perspective view of the holder carried by one of the clamp members of the attachment.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The coupling 1 is a sleeve or a collar usually employed to support the pump-rod, and this coupling is secured to the pitman or other connecting part, as the case may be, of the windmill. The attachment is adapted to be secured to the coupling 1 and is of a construction permitting application to differentsize couplings, as will be readily seen hereinafter. The pump-rod 2 passes through the coupling 1, the lower end being connected to the pump-operating devices in the usual manner. \Vhen the pump-rod is being actuated by the windmill or other power device, it is necessary to connect the same in some manner to the coupling 1, and a pin is usually employed for this purpose, which pin is carried by the coupling and by engagement with the pump-rod operatively connects these two parts together.

It is a special feature of this invention to provide an attachment carrying the engaging pin which may be applied universally to all kinds of couplings in use. The attachment consists of the clamp members 3, secured together upon opposite sides of the coupling by bolts or like fastening-s L. The bolts t pass through elongated openings 5 and are therefore adjustable so as to admit of securing the attachment to large or small sized couplings. One of the clamp members 3 is provided with a holder 6, in which a pin T is slidably mounted. The holder 6 is preferably integrally formed with the member 3, by which it is carried and is provided upon upper and lower sides thereof with slots 8. The front and rear sides of the holder may be cutaway, if desirable. Atransverse pin 9 is secured to the engaging pin 7, and the ends of the pin 9 extend into the slots 8 of the holder and guide the longitudinal movement of the pin '7 when the latter is being operated into and out of engagement with the pump-rod 2. The pin 9 also serves in the capacity of a stop, between which and the outer end portion ofthe holder 6 is interposed a coil-spring 10, said spring normally exerting a pressure against the pin 9 to hold same projected into engagement with the pump-rod 2. Upon the outer end of the holder 6 and journaled to the outer end portion of the pin 7 is a cam-disk 11, provided with cams 12 and having a lever 13 extended therefrom. The cams 12 of the disk 11 cooperate with a second transverse pin 14 to throw the pin 7 out of engagement with the pump-rod and hold said pin in such position against the tension of the spring 10. The cooperation of the camdisk and the pin 14 is caused by actuation of the lever 13, downward movement of the said lever imparting a longitudinal or slidable movement to the pin 7 to effect the desired result before described. To limit the move- .ment of the disk, a projection 15 is formed upon one of the cams 12, which projection when engaged by the pin 14 constitutes a stop preventing rotation of the disk other than to carry the pin 7 out of engagement with the pump-rod.

The pump-rod is provided with an opening within which the pin 7 is received when the latter is disposed in engagement with the pump-rod, said pin extending through the opening thereof. The clamp member 3 opposite the clamp member carrying the holder 6 is provided with a lug 16, which is received in a recess 17 in one side of the coupling, so as to more firmly hold the attachment in place.

In order that the pump-rod 2 may be connected to a manually-operated handle, same is provided with cross-pin 18 adjacent the upper end thereof, which pin is adapted to be engaged by spaced members 19 of the handle 20. The'spaced members 19 are bifurcated to receive the corresponding end portions of the pin 18, a spring 21 holding the handle engaged with the pin and permitting ready detachment of the handle from the pin when desired.

To detach the mill-operating devices from the pump-rod 2, the lever 13 is forced clownwardly, actuating the cam-disk 11 and throwing the pin 7 out of engagement with the said pump-rod. The pump-rod is thus entirely detached and may be left in this condition, if desired, or may be connected to the handle 20 to be operated by the said handle. hen the lever 13 is thrown upwardly, the spring 10 will force the pin 7 into engagement with the pump-rod, and the coupling, which carries the attachment, may be moved upwardly or downwardly, so as to bring the opening in the pump-rod into a position to receive the pin 7.

The attachment is comparatively simple and, as will be apparent, may be readily applied to various forms of coupling devices in accordance with the manner of use of same, as hereinbefore set forth. I

Having thus described the invention, what is claimed as new is 1. In an attachment for pump-rods, the com bination with a tubular coupling, clamp-plates embracing opposite sides of the coupling, means for detachably securing the clampplates together, a holder projected from one of the clamp-plates aforesaid and provided with longitudinal guide-slots, a lock-pin slidably mounted within the holder, a guide-pin carried by the lock-pin and extending laterally therefrom, the ends of the guide-pin being received by the guideslots of the holder, a spring interposed between the end of the holder and the guide-pin of the lock-pin, and means for effecting a longitudinal movement of the lock-pin.

2. In adevice of the class described, the combination with a pump-rod, a tubular coupling receiving said pump-rod, detachable clampplates embracing the coupling upon opposite sides, a holder projected from one of said clamp-plates, a lock-pin arranged within the holder aforesaid and cooperating with the pump-rod, a disk journaled upon the outermost end of the lock-pin and provided with spaced actuating-cams, an operating-lever extending from the disk aforesaid, and a transversely-disposed pin mounted upon the end of the lock-pin and having its ends extended for cooperation with the cams of the disk aforesaid for effecting longitudinal movement of the lock-pin.

3. In a device of the class described, the combination with a pump-rod coupling, a pumprod mounted therein, an attachment comprising clamp means engaging the coupling, a holder carried by said clamp means, a pin slide ably mounted in the holder, guide members projected from the pin to direct the movement of the pinrelative to the holder, and means for throwing the pin into and out of engagement with the pump-rod.

4. An attachment for connecting pump-rods with power-operating devices, the same comprising complementary clamp members, a holder projected from one of said clamp members and provided with guide-slots, a lock-pin slidably mounted in the holder, projections extended from the said lock-pin and received by the guide-slots of the holder, a coil-spring cooperating with the projections aforesaid to throw the lock-pin into engagement with the pump -rod, a camdisk mounted upon the holder and journaled on the lock-pin, and means for operating said disk to effect longitudinal movement of the lock-pin.

In testimony whereof I aflix my signature in presence of two witnesses.
